v0.10.0

Released: 7/19/2021

This release adds two major features and a new API version. VM annotations can be used to tell ignite another system will inject interfaces into the sandbox container's net-namespace. These annotations will also tell ignite to plumb those sandbox interfaces to the firecracker MicroVM using tc_redirect. (code example)

kind: VM
apiVersion: ignite.weave.works/v1alpha4
metadata:
  annotations:
    ignite.weave.works/interface/eth0: 'dhcp-bridge'
    ignite.weave.works/interface/eth2: 'tc-redirect'
    ignite.weave.works/interface/eth3: 'tc-redirect'
    ignite.weave.works/interface/macvtap-uvnrt: 'macvtap'
    ignite.weave.works/interface/macvtap-hgfeq: 'macvtap'
    ignite.weave.works/sandbox-env/FIRECRACKER_GO_SDK_REQUEST_TIMEOUT_MILLISECONDS: "1000"
    ignite.weave.works/sandbox-env/FIRECRACKER_GO_SDK_INIT_TIMEOUT_SECONDS: "1"

It's now possible to use OS and kernel images from an authenticated private registry. Interface bonding is also enabled in the newest ignite kernels.

New base OS images and kernels have been released with the GitHub Actions release tools. The default kernel has been updated from 5.4.108 to 5.10.51.

This release consists of 12 noteworthy PR's from 4 contributors. 4 of these patches were sent by 2 external contributors. Thanks so much for using and contributing back to the project.

v0.9.0

Released: 4/12/2021

This release allows changing the internal id prefixes of VM components. This overcomes limitations /w CNI's like Weave net. A U/X improvement has been made to the VM list command to show when the container runtime state of the VM does not match what ignite has stored in the API objet.

New base OS images and kernels have been released with the GitHub Actions release tools. A k3s OS image is now pushed for amd64. The default kernel has been updated to 5.4.108.

This release consists of 37 noteworthy PR's from 6 contributors. 11 of these patches were sent by 3 external contributors. 11 patches were sent by 3 people new to the project; welcome! :) Thanks so much for using and contributing back to the project.

v0.8.0

Released: 11/9/2020

We're happy to share that ignite can now be generally configured with a central config file. Check out the docs for how to configure ignite here.

Using this new config, it's no longer necessary to remember to pass --runtime and --network-plugin with every command. You can choose your own default behavior.

Working with individual VM's is now also much less error-prone. This release includes a new API version, v1alpha3, which allows VM's to remember their runtime and network config.

There's no current tooling for migrating to the new VM API for live workloads. However, older API objects are forwards compatible, and restarting the workload should upgrade the API on disk. As always, taking any necessary backups and re-creating workloads is the safest upgrade path :)

As is tradition, we have fixed bugs: networking bugs, lifecycle bugs, little UX things -- check the list.

It's now possible to run ignite within nested container environements such as containerd-within-docker and WSL2. Detailed documentation for containerized setups will graduate from issue comments to the latest docs site soon.

It's really notable that our e2e test suite is getting more complete! It's great to work with a project where confidence improves with every new patch, haha!

Alongside this release, we've updated all of the base OS images with new release tools powered by GitHub Actions. We're not shipping any new kernels, so the default is the same as before -- new kernels will be pushed in an upcoming release.

This release consists of 52 noteworthy PR's from 10 contributors. 37 of these patches were sent by 6 external contributors. 7 patches were sent by 5 people new to the project; welcome! :) Thanks so much for using and contributing back to the project.

v0.7.1

Released: 13/07/2020

The first patch release in the v0.7.X series pulls in an important fix for the long-standing networking issues in Ignite, with #638 merged you should be able to seamlessly integrate with different CNI providers and implement multi-node networking with Ignite VMs.

v0.7.1 also brings improvements to the GitOps functionality courtesy of @luxas and link checking improvements by @dholbach. Thanks!

v0.7.0

Released: 02/06/2020

We're excited to cut a large release. This release consists of 57 noteworthy PR's from 13 contributors. 27 of these patches were sent by 8 external contributors -- thanks so much for using and contributing back to the project!

Among some of the many patches, VM's can now be started in parallel. (Images should be pulled beforehand) The ignite ssh and ignite exec commands now share a native go implementation. We've added the ignite cp command along with improved CLI UX through filtering, templating, and examples. You can now also create and run VM's imperatively using YAML files with the --config flags.

Performance and stability improvements in VM and network lifecycle should make using ignite more pleasant, and the various bugfixes allow newer versions of Ubuntu to start functioning.

Lastly, we're announcing initial support for ARM devices. Our docker images for ignite-kernels as well os our OS images for Ubuntu and kubeadm now ship with a manifest list and {}-arm64 tag. We've pushed a fresh set of kernel and OS images to dockerhub to support this. Check out our new guide for ARM -- try it out on your ARM server or RaspberryPi and let us know how it works for you.

It was difficult to condense all of that!

As a special note, Sunny(@darkowlzz) from the @StorageOS team has joined ignite as a maintainer. Thanks for all of your help, Sunny!

v0.6.1

Released: 02/10/2019

We're excited to release v0.6.1 with usability improvements and lots of bug fixes :)

This release consists of 32 noteworthy PRs from 6 contributors over the past month.
We had 7 contributions from 4 external contributors. Thanks so much!

Ignite should now work with most installations of containerd -- even those that are installed underneath upstream docker.
Care has been taken with our installation instructions to ensure we are not breaking users docker installations.
We've also implemented a graceful fallback to older containerd-shim versions and now support containerd-shim-runc-v2.

This release also contains numerous fixes that make the CNI network plugin work much more reliably.
Connections to the internet from vm's using CNI should now work on most machines by default.
Please see the following user-facing change.

Default CNI Network Change

The default cni0 bridge has changed to a new ignite0 bridge introduced by the #460 bugfix. This comes with a new subnet as well.
We did this because the default CNI config shipped in v0.6.0 was a non-working configuration for most users.
You may continue to use the default CNI configuration. Nothing will change automatically.

If you are using your own CNI configuration, this does not affect you.

To migrate your running CNI networked vm's to the new default subnet, you can:

  1. install this new ignite version
  2. stop the relevant vm's
  3. delete the CNI network
  4. restart them

Example:

# first, upgrade to ignite v0.6.1

# list all vm's on the default 172.18.0.0/16 CNI network
sudo bin/ignite vm ls | grep '\b172.18.[0-9][0-9]*.[0-9][0-9]*\b'
# stop the listed vm's with the appropriate runtime
sudo bin/ignite stop my-containerd-vm
sudo bin/ignite stop my-docker-vm --runtime docker

# remove the old CNI network config
sudo rm -rf rm /etc/cni/net.d/
# optional: remove the old bridge
sudo ifconfig cni0 down
sudo ip link delete cni0

# restart your vm's
sudo bin/ignite start my-containerd-vm
sudo bin/ignite start my-docker-vm --runtime docker
# Your vm's will now have addresses configured in the 10.61.0.0/16 subnet.
# If they did not have internet connectivity before, they now should.

Enhancements

Bug Fixes

  • Change default CNI network name, bridge name, and subnet #460, @stealthybox
  • Chain firewall plugin to fix routing for default CNI bridge #442, @stealthybox
  • Teardown IPMasq rules for all actual configured bridges instead of using the hardcoded default string (#461, @stealthybox)
  • Fix containerd resolv.conf + DHCP behavior (#441, @stealthybox)
  • Make getIPChains more precise and less failure-prone (#426, @stealthybox)
  • quick fix typo umount as unmount in preflight check (#415, @chanwit)
  • fix possible dm snapshot leaks (#381, @chanwit)
  • make rm command more robust with addition check (#413, @chanwit)

v0.6.0

Released: 30/08/2019

Welcome to the v0.6.0 release, consisting of major underlying improvements, and a more efficient runtime.

This release consists of 25 noteworthy PRs from 4 contributors; although v0.5.0 was released just two weeks ago! We had 5 contributions from 2 external contributors, thanks 🎉!

The main themes of this release has been:

  • containerd is now used as the default container runtime for higher security and speed, and less resource usage
    • This means that Ignite doesn't depend on docker anymore!
  • CNI is now the default networking plugin; by default the bridge and portmap plugins are used
  • GitOps Toolkit refactor is complete; now everything you need to create your Git-backed application is available at https://github.com/weaveworks/gitops-toolkit
    • Ignite is using this toolkit internally to perform its GitOps capabilities, now you can easily use this functionality, too!
  • Bugfixes and usability improvements all around the place

Also, our documentation is now available at https://ignite.readthedocs.org. Check that site out whenever you need some information, or open an issue :)

Internal Improvements

v0.3.0

Released: 18/06/2019

Major release with significant UX and internal improvements:

  • There is no longer a difference between an Ignite image and an OCI image, this is now the same thing.
    • Ignite operates on OCI images directly, for both OS images and kernels. The kernel is expected to be coupled with the image given to ignite run, in /boot/vmlinux.
  • It is now possible to do ignite run [OCI image] directly, and everything (e.g. pulling the image) is handled automatically. e.g. ignite run -i weaveworks/ignite-ubuntu.
  • Now ignite images shows OCI images that are cached and ready to use, and ignite kernels the kernels already imported from base images.
  • Added an example usage guide for running a Kubernetes cluster in HA mode using kubeadm and Ignite.
  • Removed ignite build, and ignite image/kernel import; as these are no longer needed
  • Importing an image from a tar file is no longer possible, package the contents in an OCI image instead
  • Added a new command ignite ssh [vm] and flag: ignite run --ssh. This allows for automatic SSH logins.
  • Now Ignite logs user-friendly messages by default. To get machine-readable output, use the --quiet flag.
  • Ignite now requires the user to be root. This will be revisited later, when the architecture has changed.
  • The command outputs and structure is now more user-friendly.
  • Fixed several bugs both under the hood, and user-affecting ones

v0.2.0

Released: 06/06/2019

Major release with significant improvements

  • Ignite is now using devicemapper under the hood, for overlay snapshots for filesystem writes, allowing for image reuse, efficient use of space and way faster builds!
  • Added sample Ubuntu 18.04 and CentOS 7 OS images & a 4.19 kernel build
  • Automatic network configuration, now the OS image doesn't need to enable DHCP, as that is done in the kernel
  • Automatically populate /etc/hosts and /etc/resolv.conf, too
  • Add an option to bind a port exposed by the VM to a host port (ignite run -p 80:80)
  • Add an option for modifying the kernel command line (ignite run --kernel-args)
  • Add an option to copy files from the host into the VM (ignite run --copy-files)
  • Add an option to specify the amount of cores, RAM, and overlay size (ignite run --cpus 2 --memory 1024 --size 4GB)
  • Removed the need for the Ignite container to run with --privileged
  • Allow for force-deletions of images, kernels and vms.
  • Added documentation.
  • Moved repo from luxas/ignite to weaveworks/ignite

Use it

Download the attached binary, add it to $PATH, and execute the following commands:

$ ignite build weaveworks/ignite-ubuntu:v0.2.0 \
    --name ubuntu-image \
    --import-kernel ubuntu-kernel
$ ignite images
$ ignite kernels
$ ignite run ubuntu-image ubuntu-kernel --name my-vm
$ ignite ps
$ ignite logs my-vm
$ ignite attach my-vm

# Cleanup
$ ignite stop my-vm
$ ignite rm my-vm
$ ignite rmi ubuntu-image
$ ignite rmk ubuntu-kernel

Also make note of the known limitations

v0.1.0

Released: 31/05/2019

This is the first, proof-of-concept version of Ignite. It has all the essential features, and a pretty complete implementation of the docker UX.
